Abstract (en)
[origin: WO2012076753A1] The invention relates to a fuel injection apparatus (20) for a piston engine comprising a fuel injector body (25) in which an injector needle (40) is provided, which injector needle is arranged to prevent or allow fuel injection flow from the injection apparatus based on the position of the injector needle, which position is effected by a pressurized control fluid (63) so that by applying the pressurized control fluid the needle (40) may be urged towards its closed position and by reducing the pressurized control fluid the needle may be allowed to move away from its closed position, the injection apparatus further comprising a flow path (80,75,69,85,90,71) for the control fluid, wherein the flow path for the control fluid comprises a restriction section (71,69) providing a restriction effect to the control fluid flow. The restriction section (71,69) comprises at least one temperature-effected member (65,71) providing a temperature-dependent restriction effect. The invention relates also to a piston engine and method of operating piston engine.
